To all whom z't may concern:

Beit known that I. EDWARD citizen of the United States, and a resident of New York, borough of Manhattan, in the county of New York and State of New York7 havel invented certain new and useful Im rovemcnts in Locks, of which the follow# ing 'is a full., concise, and exact description, such as will enable others skilled in the art to practice my invention.

My invention relates tolocks and more particularly to door locks and the main ob `iect of my invention -is to produce a lock of few and simple parts which may be interchangeably used as a safety lock operable from either side of the dooior a dead lock which can be operated only from the outside of the door by a properly constructed key.

In accordance with the general features of my invention there is provided mecha.w nism located within the easing of the lock and accessible only in the unlocked position of the bolt, which may be operated by the user to make the lock a dead lock whereby it is operable only by the proper key and freno. the outside of the door or it may be made en ordinary safety lock operable by hand from the insideot the door or by key from the outside fof the door. More specifically, my invention coinprisesa pair of adjustable pins or plungers carried by a member operable by `the key mechanism and adapted in their operated positions to engage the locking bolt under different conditions to move it into andout of engagement withv its cooperating socket.A One of, said pins when in operative position to thc bolt remainng in engagement therewith when said :bolt is in its locked position to prevent lthe Amovement thereofrl except by act of tur ing the key in `the lock, the other of said pi s being adapted to engage said bolt in the operation otr moving it hy means of the key. and to be die engaged therefrom when said bolt .is in either of its extreme positions to which it must be moved in order to ermit the removal of the key from the loc As a further feature of this invention; means arcprovided whereby the lock when it is set as a dead lock and operated by the key it will automatically be reset to a safety position and can beset again as a dead lock only by hand and from the inside of the door. For this pur rose'n'ieans areprovided for engaging `the ead lock pin when the bolt is moved to the extreme of its unlocked E. GAGE, a

position to rendersaid dead lock pin inoperative and the safety lock pin operative.

In the drawings, 5 designates a casing within which is located a locking bolt or l soci. ng means-6 adapted to register with a iet- 7 in the door casing.` The bolt/6 iS ilrovided on. its inner end with aproiecting portion 8 which has formed in 'one face thereof an elongated recess 9, the other fece" being fiat and adapted to bear against the inner tace of the casing 5 which serves as e guide for one side. of said bolt 6 the opposite side of which is providedwith a Harige 10 working .in a guideway 11 of an attaching plato 12 by means of which the inner part ol the lock is secured to the door. A second projection 13Von the bolt G located near the center thereof is provided with a sloping faced cam surface 14. `Located within the casing 5 is a cylindrical member 15 having a iattened portion 16 upon which is mounted a centrally pivoted lever 17 to the opposite 'ends of which are secured pins o r plungers 18 and 19. These pins or plunger-s 18 and 19 project through the end of thecylindrieal member 15 for the purpose lhereinafter set forth. i

The cylindrical member 15 is secured bv` means of a shank 20 to a key barrel or guide 21 rotatably mounted in a cylinder22 carrying spring pressed tumblers or plungers 2% 'the key can be inserted into or withdrawn lesV from the lock only in one positionof the barrel or guide 21. vAnlopenin 26 in the relais!l ing 5 renders the pins or p ungers 1-8 and 19 normally accessible whenthe bolt 6" is in v its unlocked position but is covered by the projecting Aportion 8 when the bolt is in its locked position. The pins or plungers 18 and 19 are reciprocal in their action, that is pressure upon the plunger 18 to move it inwardly will cause the plunger 19 t'o move outwardly and pressure upon the plunger 19t-o move it inwardly will move'the plunger 18 outwardly. In order to make the lock a dead lock or one which can be operated only by a key from the outside of the door, it will be necessary to push the pin 18 inwardly thus causing the pin 19 'to move outwardly with the major portion thereof projecting beyond the end of the cylindrical member 15. suming that the bolt 6 is in its unlocked position as shown in Figs. 1 and 3, the projecting portion 8 will be in a position to uncover the opening 26 thus exposing the pins 18 and 19 to one inside the door, In the operation the key will iirst be inserted and the lock turned through a slight angle sufficient to bring the end of the pin 19 above -the upper edge of the bolt 6 where it will be free to move outwardly when pressure is exerted upon the pin 1.8 which maybe done by the finger or a pencil or like means which will enter the opening 2G. When the pin 19 is moved outwardly in this manner the pin 18 will be in and its end will clear the bolt 6 upon theturning of th cylindrical member 15. Now upon the continued rotation of the key 25 the projecting end. of`

the pin 19 will engage in the elongated re'- v cess 9y in the' projectlng portion 8 and will 4be removed from the barrel 21.

y reason of this engagement move the bolt 6 into engagement with the socket 7 vin the door casing. A complete rotation of the key 25 will bring it into a. position -where it may This movement, however, will havebrought the pin 19 back to the same angular' position in which it was when the key was first inserted into the lock but instead of being adjacentthe cam surface 14 it will be in the recess 9 and .the bolt 6 will be in its extended position with the projection. 8 fully covering' the opening 26 in the casing 5 thereby prevent- Ving manipulation of the pins 18 and 19..

The pin 19 now being in engagement with the recess 9 operation of the bolt' 6 is impossible without turning the barrel or key guide 21 and this is possible only by the removal of the tumblers or plungers, 23 from the. barrel 21 which can only be accomplished by means of` the proper key.'

The opening '26 now being cov-ered. by the projecting portion 8 of the bolt 6, operation of the bolt from the inside of the door-is wholly impossible Without removing the cas ing 5 since the cylindrical member will haveI tobe freed from the bolt 6 which can only be done by reversing the positions of the -pills 18 and 19. In unlocking the door by which it was turned to lockthe door whereupon the pin` 19 by reason of its engagement with the recess 9 will move the bolt (3 back! wardly and a complete revolution of the cylindrical member 15 will move the pin 19 from engagement with the recess 9 and cause the projecting end olf said pin 19 to engage the sloping cam face 1-'lof the projection 13 on the bolt to push said'piu 19 inwardly then throwing the pin 18 outwardly. In this position of the parts the bolt 6 isentirely free of the cylindrical member 15 and may be -moved bacluvardly and forwardly by one on the inside through the agency of a knob 30 orby operation of the key from the outside the pin 18 may be caused to engage the recess 9 to move the bolt (5 in'either direction. Due, however, to the fact that the key has to be moved through a complete revolution in order to remove it the pin 19 cannot be left in any' pin 18 or 19 the lock may be made a safety lock operable by hand from the inside or a dead lock operable only by the key from the outside of the door.' l

While the bolt 6 is shown and described as being operable manuallyfrom the inside or by a key from the outside, it is quite obvious that it might be moved into engagement with the socket 7 in the door casing by means of a spring.

Having now described my which may vary in detail .without departing from the spirit thereof, what I claim, and desire to secure by LettersPatent, is-

1. In a lock, a securing member, arctatablc member, a key for operating said rotainvention,
